"Argh, um, ooh... actually that's kinda interesting" is an approximate record of my thoughts as I heard the Time Harp play in this vid for the first time. The robo-musical instrument grinds plastic discs against strings to make them resonate, activated by motion sensors. And it produces...well, a kind of vooming hum that is almost, but not quite, entirely unlike the sound of Dr Who's TARDIS dematerializing. Designed by Larnie Fox, I like it for its low-tech strangeness and eerie sounds. Plus its the sort of sound that'll pop up in the background of some dance tune or other, and now you'll know where it came from. [Makezine via Crunchgear]
